Motor 2 Control Parameters
When logic inputs assigned to functions 39 or 40 are active, parameters F170 to F173 and F185 are the
active set of motor control parameters.
When motor 2 control parameters are active, only constant V/Hz Motor Control Mode ([Mot cont. mode sel.]
(Pt) = 0) is available (see page 67
).
Code Name / Description Adjustment range Factory setting
F170 [Mot 2 rated Freq.]
Motor 2 rated frequency 25.0 to 200.0 Hz 50.0 Hz
Set parameter F170 to the motor’s rated frequency as indicated on the motor nameplate.
Note: It is possible to set the drive’s various motor control frequencies to 50 Hz by setting [Parameter reset] (tYP) to 1, the
50 Hz reset. For more information, see page 62
.
F171 [Motor 2 rated Volt]
Motor 2 rated voltage According to drive
rating (1)
According to
drive rating (1)
Set parameter F171 to the motor’s rated voltage as indicated on the motor nameplate.
ATV212
pppM3X: 50 to 330 V.
ATV212
pppN4: 50 to 660 V
Note: Drive output voltage cannot be set to exceed the input line voltage.
F172 [Motor 2 Volt Boost]
Motor 2 voltage boost 0 to 30% According to
drive rating (1)
F173 [Motor 2 Overload]
Motor 2 rated current overload setting 10 to 100% of the
drive’s output cur-
rent rating
100%
Set parameter F173 to the motor’s rated current as listed on the motor nameplate for the selected operating voltage.
F185 [Mot. 2 current limit]
Motor 2 current limit 10 to 100% of the
drive’s output cur-
rent rating
110%
CAUTION
RISK OF DAMAGE TO THE MOTOR AND THE DRIVE
z Check that the motor will withstand this current.
z Check that the profile mission complies with the derating curve given in the installation manual.
Failure to follow this instruction can result in equipment damage.
Adjust parameter F185 to limit current during motoring or braking.
Do not set parameter F185 below the no-load current rating of the motor; otherwise, the drive will determine that motor braking
is taking place and will increase the frequency applied to the motor.
F401 [Slip Compensation]
0 to 150% 50%
Before adjusting parameter F401, verify that parameter [Motor rated speed] (F417) (see page 70) is set to the rated
speed of the motor in rpm. Parameter
F401 can be used to fine tune the drive’s slip compensation feature. Increasing
the value of parameter
F401 increases the drive’s compensation of motor slip.
F402 [Auto Torque Boost]
0.0 to 30.0% According to
drive rating (1)
Use parameter F402 to adjust the amount of automatic torque boost that is applied.
